Are self-signed certificates for the domain server allowed to your system?

As of the moment, self-signed certificates are not supported by the system.

We suggest these possible solutions :

  1. Using Let'sEncrypt, which is also free.  Their certificates are broadly accepted.
  2. Using a secure tunnel towards e.g. an HTTP-only service.  E.g. by using the service from or similar which will provide an acceptable HTTPS connection.
